We just rolled out Revit MEP 2011 and I have a quick question about the new cable tray feature. Is there a way to apply a hatch pattern to the surface, or modify the material? I see that they're system families, so the "edit-ability" is limited. We currently use a custom made family that looks great on the drawings, but cumbersome to use. The new command would work great if we could only add a surface pattern to it.
I would appreciate the advice. Thanks.
